Thanks, she is really shiny, and she's been a very good layer too.
I had thought about hatching eggs, and love the idea of that, especially with the kids, but my town has a noise ordinance against roosters, and it would be terrible to have to get rid of any of the chicks - if they hatched a male. Too worrisome.
I think that - 'slow broody' is a spot-on description - & this sounds just like your hen. She is still laying like normal... but passing the large broody dropping in the morning and hovering too long on the nest after she's laid. Yet, after I fluff her off the nest, she stays off & doesn't generally go back to the nest... just walks around being cranky.
This morning, I went out to get her and she didn't puff up, or act nasty at all. There were no grumbles either, so these are good signs! 2 days/nights in the jail, and maybe it's worked? And the Pinless Peepers are out for delivery now! I can get them on her asap - and let her go back with the rest of the flock, & hopefully she'll have a new outlook.
I picked her up and pet her, when I carried her into the coop and she was ok - a little shook up from being in exile - but she calmed when I pet her. She went right onto the nest & I've set a timer for about an hour, to go check on her... and hope she's not going back to broody, but she has to lay... but now I'm hoping there's no egg bound issues. Though I put a nest in the crate for her yesterday for a few hours - and she didn't lay on it at all. I hope this is all going to smooth out soon! Thanks again to everyone, and thanks
